Trial Week

Live together for a week before you sign.

Answer honestly about habits, watch seven simulated days under one roof, practise the clashes, then write your house agreement together.

What are you about to start?

Step 1 . Invite

You

Them

Each person's raw answers stay private. You both only see the simulation and the report.

Step 2 . Habits and values

Slide to where you really are

Not where you wish you were. The demo shows both people's answers so you can see the gaps.

Building your week

Moving you both in

Step 3 . Your simulated week

Step 4 . Compatibility report

By area

Your strengths together

3 things to agree on upfront

How you each handled friction

Step 5 . House agreement

Generated from your week

After move-in . Weekly check-in

Every Sunday evening you each rate the week in 20 seconds. Trial Week tracks your house harmony and suggests one small edit to the agreement when something slips.

The grand mission

Make every big living or working partnership start with eyes open.

Flatshares, co-founder splits and friendships ruined on a trip almost always fail on things that were predictable: dishes, guests, money, sleep, who decides. Trial Week lets you rehearse the hard parts before the lease, the cap table or the plane ticket.

Year 1

Flatmates, couples moving in, co-founders and travel buddies in 15 languages. Flatshare sites offer a Trial Week badge on listings.

Year 2

Accelerators require a co-founder Trial Week before demo day. Real check-in data makes the simulations sharper with every pair.

Year 3

The normal first step for any big shared commitment. Fewer broken leases, fewer founder breakups, more friendships that survive the road trip.

Blueprint

1. The mission

Before you move in, start a company or travel with someone, live a realistic simulated week together. See where you'll clash, practise how you'd handle it, and start with a written agreement instead of silent assumptions.

2. Why people can't resist it

Self-discovery as a story. Watching "you" and "them" through a week is like a personalised sitcom.
Curiosity about the other person. "Would they really leave the dishes?" is irresistible.
Permission to talk. The app raises awkward topics (guests, money, noise) so neither person has to.

3. How it works for real

Questionnaire. 10 to 16 sliders per person on habits and values, plus optional free text. Raw answers are private.
Friction model. Plain code turns slider gaps into weighted friction risks per area (sleep, noise, cleaning, guests, money, food, space).
Week writer. A frontier LLM (Claude via OpenRouter) writes 7 days of short, specific scenes in each person's city and language, with 3 to 5 friction moments chosen from the biggest gaps.
Response options. The LLM writes 3 realistic responses per moment (avoid, direct, compromise). Each person picks privately; a cheap model (Gemini Flash or DeepSeek) scores the outcome.
Scenes. Free tier uses illustrated SVG scenes. Paid tier renders a 20-second "your week" recap with an image model for stills and a video model (Seedance or Wan) for motion, with TTS narration.
Report and agreement. Claude writes strengths, the 3 things to agree upfront and a house agreement from the actual picks.

4. Cost per use

Text simulation and report: about $0.03 to $0.08 per pair.
Video recap: 20 seconds at roughly $0.10 to $0.25 per second, so $2 to $5. Paid only.
Free: one Trial Week with still scenes and the agreement. Paid: $7 per pair for video recap, unlimited re-runs and check-ins. B2B: flatshare platforms, accelerators, student housing.

5. Growth loop

Every Trial Week needs two people, so every user invites one. The share card ("We scored 78, we're agreeing on guests upfront") spreads in friend groups and flat-hunting chats. Listings with a Trial Week badge attract better matches. After move-in, a 20-second Sunday check-in rates the week's friction, plots your house harmony trend and proposes small agreement edits, so both people come back every week.

6. Risks and guardrails

Privacy: raw slider answers and notes are never shown to the other person, only the simulation.
No hidden scoring of people: the score is about the pairing, not a rating of anyone's worth.
Discrimination: questions are about habits, never about religion, ethnicity or orientation; listings cannot filter on those.
Safety: if answers suggest control or abuse in an existing relationship, show resources instead of a score.

7. MVP build order

Invite flow and the slider questionnaire for two people.
Friction model plus LLM-written week with 3 friction moments and response picks.
Compatibility report and generated house agreement.
Share card and the week-1 check-in by email or WhatsApp.
